Develop UI component plugins

With Openblocks plugins, you can develop customized components that are consistent with native components for your specific scenarios.
Initialization
Execute the following yarn start file:
# Project initiation
yarn create openblocks-plugin my-plugin
​
# Go to the project root
cd my-plugin
​
# Start the development environment
yarn start
Component development environment
After executing yarn start, the browser is automatically opened and you enter the component development environment.
Plugin configurations
In openblocks field in package.json file, you need to define the component properties. For example, the following is the explanation of several fields:
comps defines UI components contained in the plugin. For each component, the key name of the object is the unique identity, and the value is metadata.
comps[someCompKey].name defines the component name shown in the Insert tab.
comps[someCompKey].icon defines the component icon shown on the canvas. Use a relative path to where package.json file is located.
comps[someCompKey].layoutInfo defines the component layout:
w: width of the component. Counted by the number of grid cells (range: 1 - 24).
h: height of the component. Counted by the number of grid cells (range: >= 1).
  "openblocks": {
    "description": "",
    "comps": {
      "hello_world": {
        "name": "Hello World",
        "icon": "./icons/hello_world.png",
        "layoutInfo": {
          "w": 12,
          "h": 5
        }
      },
      "counter": {
        "name": "Counter",
        "icon": "./icons/hello_world.png"
      }
    }
  }
Export components
To export all the components, use src/index.ts, for example:
import HelloWorldComp from "./HelloWorldComp";
​
export default {
  hello_world: HelloWorldComp,
};
The default exported object key needs to be consistent with the key configured in comps in package.json file.
Publish plugins
When you finish developing and testing the plugin, you can publish it into the npm registry. Login in to the npm registry locally, and then execute the following command:
yarn build --publish
If you do not specify the parameter --publish, the tar file will be saved in the root folder.
Import plugins
In the Openblocks app, click Insert > Extensions > Add npm plugin in the right pane. 
​
Input your npm package's URL or name, and then you can use your customized components.
my-plugin
​
# or
​
https://www.npmjs.com/package/my-plugin
